Zeuss carries a February 2026 federal warning letter for false and misleading claims, addressed to the company at the email address on this very site. It sells GHK-Cu only inside a three-ingredient hair formula, so it publishes no copper-peptide price at all.
What Zeuss charges
Zeuss does not publish a price today.
Zeuss also sells 1 compound this site boards without publishing a price for it: GHK-Cu.

The letter, and why it attaches
A warning letter issued in February 2026 names Zeuss LLC, trading as Zeuss, and is categorised as false and misleading claims and misbranding in a telehealth context.
It is attached to this record on the entity, not on a coincidence of names. The letter's recipient block carries the support address at this domain, and its opening line says the agency reviewed the website content at this site's own web address.
The company was then queried for siblings in the same federal table. It appears once, and no other seller on this roster matches it.
GHK-Cu is an ingredient here, not a product
Both hair formulas Zeuss sells list a copper peptide alongside two other actives, with each ingredient's strength printed.
No price is recorded against GHK-Cu for that reason. A three-drug formula's figure filed under one of its ingredients would put a number on the copper-peptide board that this seller never attached to copper peptide.
The compound is still declared, because the seller genuinely dispenses it. What is absent is a price scoped to it.
What the site does say clearly
Zeuss states that compounded medications have not been approved by the FDA and that the agency does not verify the safety, effectiveness or quality of compounded drugs.
It names Zeuss LLC as the operating company in its own terms, repeatedly, which makes the entity checkable.
It offers a full refund if a physician cannot prescribe treatment, and prints the milligram strength of every ingredient in its formulas.
The rest of the record
No list of served states is published.
No dispensing pharmacy is named and no certificate of analysis is reachable.
A warning letter is not a finding about the drug a patient receives. It is a finding about what a company said, and it is on the public record either way.
Who it's for
Readers who want to see what a lettered telehealth seller looks like before buying from one.
Buyers who want an operating company named in the terms.
Shoppers who value ingredient strengths printed on the product page.
Anyone comparing hair formulas that contain a copper peptide.
Who should look elsewhere
Readers who want GHK-Cu on its own rather than in a blend.
Anyone unwilling to buy from a company with an open warning letter.
Buyers who need a state list or a named pharmacy.
Shoppers who want published testing.

Trade-offs

Publishes no state list and names no dispensing pharmacy
No certificate of analysis is reachable
FDA disclosure
Zeuss received an FDA warning letter issued February 2026. A warning letter discloses; it does not, on its own, disqualify a provider — see the trade-offs above for what this one concerned.
How we verified this
Screened the brand and the company against the live federal warning-letter table, filtering locally because the table's own search parameter returns every record whatever is typed into it.
Fetched the letter itself and confirmed its recipient email and the web address it reviews both belong to this seller.
Requested a deliberately meaningless letter address on the same federal host in the same session and confirmed it returns a not-found response, so the letter's success code means a real page.
Queried the company for sibling brands in the same table and confirmed it appears once and matches no other roster seller.
Declined to record a GHK-Cu price, because every published figure buys a three-ingredient blend.
A provider to compare Zeuss against
Auren Rx
Auren Rx names both its prescribing group, Wasef Health, and its dispensing pharmacy, VialsRX in Houston, with street addresses and phone numbers, and lets a subscriber pause an auto-refill plan on NAD+, sermorelin, glutathione or GHK-Cu instead of forcing a full cancellation.
It is categorised as false and misleading claims and misbranding, in a telehealth context, and was issued in February 2026. It concerns what the company published, not a defect found in a specific medicine.
Are you sure the letter is this company?
Yes. The letter's recipient block carries this site's own support email address, and its opening line names this site's web address as the content the agency reviewed.
Why is there no GHK-Cu price?
Because every figure Zeuss publishes buys a formula containing a copper peptide plus two other actives. Filing that number under GHK-Cu would misdescribe what the money buys.
Does a warning letter mean the product is unsafe?
It does not say that. This letter is about claims and labelling. It is a matter of public record and worth knowing; it is not a finding about what arrives in the box.
